I can only speak for my K4B but yes the button are easy to push now. I don't drop it trying to turn the page. A little push and the page turns.

On my K4S I have to click the button so to speak and I lost my grip in trying to do so well now I don't because the buttons are worn enough but they were really stiff for the first year. On the K4B it's more easier to turn a page now almost as easy as the K3.

The other button that has changed is the power button it's sits farther back now making it hard to push. I am told the PW also has this design with the power button. This is the only negative I can think of after using my K4B for over a week now.

Thank you so much Blossom! I always find your posts very informative. Keep up the good work!

I use my K4B with a Eco-flip case that has a hand hold in the back. I love that case! It's only $25 now. I plan to get another one for the PW next month when I buy them together. The only negative with the case was it stained my silver K4's back but I think a piece of black felt or paper would keep that from happening.
